If anyone in the USA or UK has applied sor the SANEF Telepeage transponder and had it delivered to their home address before heading for France, please respond with the process you used. We will travel in France from Paris to Reims to Beaune to Avignon and the Provence area in September and October of this year. Thanks.
I've not used it myself, but I found this website which appears to offer what you're looking for: http://www.tolltickets.com/country/france/libert.aspx?lang=en-GB
